Fast Activated Cell-based ELISA (FACE™ In-Cell Western) Kits provide a simple, sensitive method for detecting protein phosphorylation directly in the cell, without making extracts or performing electrophoresis and membrane blotting. These 96-well, high-throughput In-Cell ELISA assays are available in both colorimetric and chemiluminescent formats for over 20 different targets (see list at right). If you need an In-Cell ELISA Kit for a target that is not currently offered, you can use our FACE Maker In-Cell Western ELISA Kits to create your own FACE assays.
